English Wikipedia has an article on:


climate change (uncountable)

  2. Large-scale and long-term change in the Earth's climatic system produced by global warming; anthropogenic climate change.

Usage notes[edit]

May be treated (in the sense “anthropogenic climate change”) as a synonym of global warming in informal contexts, particularly in regions where climate science is contested by political actors. This conflation is not widespread in scientific contexts, where it may be regarded as incorrect.
